The Worldcoin Foundation has introduced a new system for biometric template protection, developed with TACEO’s cryptography engineers. This system, using <a href="https://chain.link/education-hub/secure-multiparty-computation-mcp">Secure Multi-Party Computation (SMPC)</a>, allows for the secure deletion of the previous iris code system. 
<h2 class="p2" id="data-collection-revamp">Data Collection Revamp</h2> 
Worldcoin’s new approach, now open-source on GitHub, encrypts iris codes into multiple secret shares distributed among various parties. These parties work together to compute results over the encrypted data without accessing the actual secrets, ensuring a high level of privacy for verifying biometric templates’ uniqueness. 
A Worldcoin Foundation representative stated, “By migrating to SMPC, we’ve achieved a significant enhancement in privacy protection for our users. After securely transferring all iris codes to the new system, we deleted the old data.” 
Recent optimizations in SMPC protocols for machine learning, adapted by Worldcoin and TACEO, have made it possible to use these protocols for iris code comparisons. This system allows Worldcoin to verify an individual’s uniqueness without decrypting the biometric data. 
<h2 class="p2" id="system-transition-and-requirements">System Transition and Requirements</h2> 
The transition to the new system was completed in March 2024. After extensive testing, the previous iris code system was securely deleted in May 2024. The new system requires substantial computing resources, including 1152 cores, 3.6TB of memory, and 5 Gbps bandwidth across all involved parties. 
<h2 class="p2" id="regulatory-hurdles">Regulatory Hurdles</h2> 
This development followed discussions with data protection authorities, particularly the Bavarian Data Protection Authority (BayLDA). Currently, Tools for Humanity and Worldcoin Foundation’s EU establishment are participants in the SMPC system, with additional third-party participants under consideration. 
The announcement comes after <a href="https://worldcoin.org/">Worldcoin</a> faced regulatory challenges in multiple countries, scrutinized over data privacy and security practices. Authorities in several regions questioned the adequacy of Worldcoin’s measures to <a href="https://insidebitcoins.com/buy-cryptocurrency/best-crypto-courses">protect user data</a>, prompting the foundation to accelerate its efforts to adopt more robust privacy technologies. 
<h2 class="p2" id="broader-privacy-and-security-initiatives">Broader Privacy and Security Initiatives</h2> 
The adoption of SMPC is part of a broader initiative by the Worldcoin Foundation to enhance privacy and security. Other measures introduced in 2024 include personal custody for secure personal information storage, the ability for users to delete their iris codes, and on-site age verification to prevent underage sign-ups. 
The new SMPC system marks a significant milestone in biometric security, setting a new standard for privacy protection in <a href="https://insidebitcoins.com/buy-cryptocurrency/best-crypto-exchanges">digital identity verification</a>. This advancement allows for secure, private verification of user uniqueness, representing a significant step forward in the field of biometric data protection.

<h3 class="p1" id="smog-revolutionizing-the-meme-coin-arena-with-its-gamified-airdrop-strategy">SMOG: Revolutionizing the Meme Coin Arena with Its Gamified Airdrop Strategy</h3> 
The meme coin named SMOG has quickly established itself as one of the premier Solana-based cryptocurrencies of the year, experiencing a surge of over 1000% in value following its launch on Jupiter DEX. This digital asset, drawing inspiration from the dragon character “Smog” in the Hobbit series, embodies a mystical theme within the Solana ecosystem, aiming to rejuvenate the meme coin market with its unique allure. 
SMOG is not just another meme coin; it has set itself apart by announcing what many are calling the most ambitious airdrop ever. This initiative includes a gamified system where token holders engage in various activities to earn airdrop points on a regular, scheduled basis. The project’s strategy incorporates daily, weekly, and monthly tasks that contribute to this interactive airdrop experience. 
The development team behind <a href="https://insidebitcoins.com/visit/smog" rel="nofollow">SMOG</a>, equipped with extensive experience in the web3 space, further reinforces the project’s credibility as a top cryptocurrency investment for 2024. The project’s dynamics are designed to mirror the initial market responses seen with other Solana-based tokens like BONK and Myro, but with added features that enhance its appeal. 
Originally, SMOG could only be acquired by exchanging SOL. However, recent developments have introduced an ETH bridge, expanding purchasing options to include ETH, and directly from the project’s website. The addition of staking capabilities has also enhanced its functionality and appeal. 
The project’s roadmap, infused with its inherently memetic nature, outlines plans for multiple airdrops that add a layer of gamification to the entire venture. SMOG aims to ascend as the leading <a href="https://insidebitcoins.com/visit/smog" rel="nofollow">meme coin in the Solana ecosystem</a>, eventually becoming the reigning SOL king. 
Recent updates have highlighted SMOG’s growing influence and success. As of early March 2024, CoinMarketCap data indicated that SMOG was among the biggest gainers, boasting a market capitalization exceeding $20 million.
